So what's the benefit of getting this? Is it compatible with 2.8 big bore heads?

You have to run more that the intake alone to get it all to fit. You have to run the throttle body and some other parts as well. I'm not sure about the benefits of the fuel rail, but here is the benefit of the manifold, S4 on top, RS4 on bottom

Thanks. yeh throttle body is on the list too. Also looking for some 2.8L big bore heads and NA cams in the long run.

Jibbber might still have his 2.8 with some work done to them already. they were pretty resonably priced.

Otherwise pick n pull/ buy the engine and part it out. But the blocks are just not as desirable as the s4 blocks. (2bolt mains vs 4 bolt mains, and no oil ports for the turbos) But they can be made to work.
